CVE-2023-34210Network attack vector

Database disclosure via customer-group SQL injection

Published Oct 17, 2023 · Updated Sep 13, 2024

SQL injection in MailHunter Ultimate 2023 and earlier allows remote authenticated users to execute SQL via a customer-group field. The customer-group creation function incorporates the ctl00$ContentPlaceHolder1$txtCustSQL parameter into a database query without neutralizing SQL syntax. A valid application account and network access to that function are required; the CNA assessment limits impact to database confidentiality.
